䳍形目（学名：Tinamiformes），在动物分类学上是鸟纲古颚总目下中的一个目，分为9属47种，是古颚总目各种鸟类中体型最少的种类，常被和鹬鸵搞混。特征是脚掌大而体型圆。䳍形目的鸟主要散布于拉丁美洲，而且由于生存环境日渐受到破坏，大都濒临绝种。

Tinamous form an order (Tinamiformes), comprising a single family (Tinamidae) with two distinct subfamilies, containing 47 species of birds found in Mexico, Central America, and South America. The word "tinamou" comes from the Galibi term for these birds, tinamu. One of the most ancient living groups of bird, they first appear in the fossil record in the Miocene epoch. Tinamous have traditionally been regarded as the sister group of the flightless ratites, but recent work places them well within the ratite radiation, implying basal ratites could fly. They are generally sedentary, ground-dwelling and, though not flightless, when possible avoid flight in favour of hiding or running away from danger. They are found in a variety of habitats, ranging from semi-arid alpine grasslands to tropical rainforests. The two subfamilies are broadly divided by habitat, with the Nothurinae referred to as steppe or open country tinamous, and the Tinaminae known as forest tinamous.
